Abstract

The present disclosure describes methods, systems, and computer program products for providing multi-level user interface theming. One computer-implemented method includes instantiating a shadow system and database schema for a new version software application in a shared database, the shadow system database schema containing aliases pointing to tables instantiated in a production database schema, instantiating a bridge database schema containing aliases pointing to each database table within the production database schema, preparing a bridge sub-system connected to the bridge database schema aliases, replicating database tables within the production database schema, for use by the bridge sub-system and adjusting the original database tables for structure and content consistent with the new version software application, deploying an upgrade sub-system and tools to complete adjustment of structure and content of the original database tables, and connecting an instantiated instance of the new version software application to adjusted database tables.
